MACHINE FCR COATING CLOTH WITH PAINT.

Specification forming part of Letters Patent No. I 5,065, dated June 10, 1856.

To all whom it 17mg concern.-

Be it known that I, DANL. CUSHING, of the city of Wheeling, in the county of Ohio and State of Virginia, have invented certain new and useful Improvements in Painting or Enameling Cloth, and the Mode of Hanging it for Drying; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making a part of this specification Figure l being-a top view, Fig. 2 being an elevation as seen from one side, and Fig. 3 being an elevation as seen from the opposite side.

To understand the importance of this invention, which is peculiarly adapted to the painting of cotton or other cloth intended as a substitute for leather, and which is now so extensively used in carriage-trimmings, covering of tables, sofas, &c., perhaps it may be as well to explain the method of coating cloth for this purpose now employed, in which it is requisite that it be cut 0E in lengths, say, of ten or twelve yards. The ends of each piece are then joined together, thus making an endless sheet. This is now stretched between a pair of rollers, and the composition or paint is applied by hand, the cloth being moved continuously until coated. It is then removed from the rollers and by the edge taken to a hanging-room for drying. XVhere small quantities of this cloth may be required and expense of manufacture is not important, this method may answer; but at best it is a slovenly way, as careless handling must more or less disfigure the side of the cloth intended to be preserved from the coating, and when it is considered the number of coats requisite it would be surprising if the cloth were not disfigured.

In my improvement in machinery for effecting the coating I make use of the friction of the cloth alone upon a rolling drum, A, or cylinder to move it under the knife, and am thus enabled to coat the cloth irrespective of thelength thereof, as it is not necessary in my machine that the ends of the cloth should be sewed together, as in the method now employed. On the contrary, the cloth, after passing around the drawing -drum A, under a scraper, B, or doctor, as it is drawn from the bolt or web axle O, on which one hundred yards or more may be rolled, is then carried under the machine and over a second stretching-roll, D, where by the adhesion or friction on this roll, as in the first instance, the web of painted cloth is stretched evenly across its whole breadth. From the second roll it passes by means of an endless belt, E, on which it is received, to a second carrying-belt, F, from which it is delivered on the bars a a a of a hanging-frame, G, movable 011 rails I) Z). By means of said frame the cloth is delivered in loops eeand hung over the bars without touching either surface thereof, and without the necessity of the least handling of the selvage, thus not only preserving the cloth H clean, but obviating a serious difficulty of stretching the selvage, by which it has heretofore been disfigured in the method alluded to, the ten sion of the cloth over and by the drums removing any wrinkles and delivering it without strain on the selvage. The hanging-frames are filled by looping the cloth over the bars. when the folds hang about two yards long. I find that in a twelve-foot frame I can hang one hundred and fifty yards of cloth two and a half inches apart thus coated. After having filled by moving the frame and bringing each bar for its fold, the frame is run oif by a suitable railway to the drying-room until sufficiently dry to receive another coat. It is then removed by rolling on a bar and again subj ected to the same process as that described. The coating or paint is kept in a tray, I, suspended over the scraper or doctor B, from which tray, when stiff, it is taken by trowels and spread on the surface of the cloth between the scraper and the web-beam, any superfluous paint being removed by the scraper, and the coating thus evenly spread upon the surface of the cloth. WVith the view of rendering the tension of the cloth more perfect as it is drawn under the scraper, a friction-clutch, h, is applied to the web-beam, and by a shifting weight the cloth may be more or less retarded, and thus produce a perfect operation of the scraper or doctor.

To enable others to construct the machine the following description will suffice:

A is a large drum receiving motion from an engine or otherwise; B, a metal scraper extending the whole width of the machine; 0, a

roller on which the cloth is wound preparatory to receiving the coat of paint.

D is a large drum of the same size as A and turning with it by suitable pulleys and band, 2.

E is an endless belt placed above the large drums, &c., passing around rollers or drums 00 0c 50, the center one receiving motion by Virtue of the driving-band z passing over it. Immediately below the center roll is placed a fourth roll,V, whose office is to keep the endless belt E from too great a sag. It also, by the band z passing over it, assists in moving the endless belt, as the weight of the painted cloth received on the belt renders this necessary. The endless belt also directs it overhead, so as to allow space under it for the workmen.

F is a second carrying-belt, moved by aband, t, passing over a pulley or roller of said carrier. This second belt is arranged on rollers 8 ss, placed between proj ecting timbersrr from the elevated end of the machine. Below these timbers are suspended by suitable braces the rails b 1), upon which the hanging-frame G is made to travel, said frame being provided with suitable friction wheels to render its movement easy.

' Having described my improvement in painting cloth, what I claim as my invention, and desire to secure by Letters Patent of the United States, is

1. The arrangement of the several rollers and belts, as described, wherein I make use of the friction of the cloth on the roller A for the purpose of giving the necessary tension and movement of said cloth, when in combination with the means of spreading the paint or composition as in the manner described, and the delivery of the cloth when coated, substan tially in the manner and for the purposes set forth. 7

2. The arrangement of the hanging-frame G, constructed substantially in the manner described, for the purpose of receiving the cloth for drying, thereby rendering the painting and hanging it a single mechanical operation.

In testimony whereof I have hereunto signed my name before twosubscribing witnesses. DANL. OUSHING.
